Incidences and Risk Characteristics of Respiratory Complications among Patients Receiving General Anes-thesia at the Operating Room and the Post Anesthetic Care Unit in Phrae Hospital

Abstract

The purposes of general anesthesia (GA) are unconsciousness and analgesia. The effects of drugs or medication used for general anesthesia included vasodilatation, hypotension, and respiratory complica-tions during the anesthetic process. Moreover, more effects of GA included receiving more treatment, increasing lengths of stay and getting worse conditions in intensive care unit. The aim of this study was to assess the incidence and risk characteristics of respiratory complications among patients receiving general anesthesia and to compare risks characteristics among between two groups which had high incidence of respiratory complications and non-respiratory complications in both perioperative and post anesthetic care unit at Phrae hospital. It was conducted as a retrospective study. Data were collected from March to October 2015. Descriptive statistics and the logistic regression were used for data analysis. As for the results, there ware 4,628 patients anesthetized in the study period. The results showed that overall, there were 2 times more female than male. The most common respiratory complications included desaturation and bronchospasm. Risk characteristics of desaturation were age >60 years (OR 7.7), ASA Classification 3 or American Society of Anesthesiologist Class 3 (OR 6.9), haste (OR 16.0), duration of anesthesia e >60 minutes (OR 4.8). Risk characteristics of bronchospasm were age >60 years (OR 3.1), ASA Clas-sification 2 or American Society of Anesthesiologist Class 2 (OR 2.7), haste (OR 4.2), duration of anesthesia >91 min (OR 6.6), Respiratory tract infection (URI) (OR 21.8), chronic lung disease (COPD) (OR 19.9). In summery, the results from this study could be used to improve quality of anesthetic services including the baseline information, prioritization of the problems and prevention, and guidance to future study.
